Configuration for vertical take-off and landing system for aerial vehicles

Andrei Evulet
TLDR
In this article, a vehicle is coupled to a main body and a fluid generator, and at least one fore and one tail conduit are fluidly coupled to the generator and the primary airfoil element.
Abstract
A vehicle, includes a main body. A fluid generator is coupled to the main body and produces a fluid stream. At least one fore conduit and at least one tail conduit are fluidly coupled to the generator. First and second fore ejectors are fluidly coupled to the fore conduit, coupled to the main body and respectively coupled to a starboard side and port side of the vehicle. The fore ejectors respectively comprise an outlet structure out of which fluid flows. At least one tail ejector is fluidly coupled to the tail conduit. The tail ejector comprises an outlet structure out of which fluid flows. A primary airfoil element is coupled to the tail portion. A surface of the primary airfoil element is located directly downstream of the first and second fore ejectors such that the fluid from the first and second fore ejectors flows over the such surface.

Flying vehicle with lift generators

Zelic Safedin
TL;DR: Aeromobil is a dynamic flying machine heavier than air which produces necessary aerodynamic force for lift, thrust and control moments in aerodynamic generators as discussed by the authors, which makes it possible for it to lift and land vertically in its own characteristic way, to soar in big altitude range, to take any direction in space by its vertical axle while soaring, to get to translational motion in any direction from every soaring position, and to get into soaring position from every direction of translation motion.
